(
Elsevier
, 2016 , Article)
With the wide adoption of cloud computing paradigm, it is important to develop appropriate techniques to protect client data privacy in the cloud. Encryption is one of the major techniques that could be used to achieve ...
Structural and magnetic studies of La2BMnO6 (B=Ni and Co) nanoparticles prepared by microwave sintering approach
(
Elsevier Ltd
, 2016 , Article)
Double perovskite La2BMnO6 (B=Ni and Co) nanoparticles were successfully synthesized by microwave sintering approach (MWS). The crystal structure properties of LBMO nanoparticles were systematically investigated using X-ray ...
Thermophysical properties of multifunctional glass fibre reinforced polymer composites incorporating phase change materials
(
Elsevier B.V.
, 2016 , Article)
In this study novel multifunctional composites consisting of glass fibre/epoxy/microencapsulated phase change materials (micro-PCMs) were prepared and their thermophysical properties have been investigated. Test results ...
Extension of the model of binary fluidization to beds confined in a packing of coarse spheres
(
Elsevier B.V.
, 2016 , Article)
The prediction of the minimum fluidization velocity of beds of Geldart's group B particles confined in a packed bed of coarse spheres can be achieved by extending to this peculiar type of systems the theory developed for ...
Synthesis of new amines for enhanced carbon dioxide (CO2) capture performance: The effect of chemical structure on equilibrium solubility, cyclic capacity, kinetics of absorption and regeneration, and heats of absorption and regeneration
(
Elsevier B.V.
, 2016 , Article)
This work focused on the synthesis of new tertiary amines by varying the alkyl chain length with/without hydroxyl group in the structure. The effect of chemical structure of newly synthesized tertiary amines; 4-(dimethyl ...
The effect of sliding speed on the wear of steel-tool steel pairs
(
Elsevier Ltd
, 2016 , Article)
This study examines the effect of sliding speed and surface temperature on the wear behavior of an unlubricated mild steel-tool steel contact pair using the pin-on-disc test. The operating conditions and contact pair are ...

(
Elsevier
, 2016 , Article)
A bio-friendly nanostructured cellulose nanocrystal (CNC) sheet with iron oxide grown on it acting as a nitrogen dioxide (NO2) gas sensor was fabricated by hydrothermal method. The structural investigation was done to ...
Propagation rate coefficient for sulfobetaine monomers by PLP-SEC
(
Elsevier Ltd
, 2016 , Article)
Zwitterionic polymers have been extensively used in the biomedical field, however, the knowledge about the kinetics and mechanism of radical polymerization of their monomers is limited. This work introduces the first ...
Corrosion protection of electrospun PVDF-ZnO superhydrophobic coating
(
Elsevier B.V.
, 2016 , Article)
A one-step electrospinning technique was used to prepare a protective superhydrophobic PVDF–ZnO nanocomposite coating for aluminum against corrosion. The wettability and morphology of the prepared coating surfaces was ...
Prevalence of microplastics in the marine waters of Qatar
(
Elsevier Ltd
, 2016 , Article)
Microplastics are firmly recognized as a ubiquitous and growing threat to marine biota and their associated marine habitats worldwide. The evidence of the prevalence of microplastics was documented for the first time in ...
